When you apply the brakes in your truck, the brake controller sends a signal to the camper’s brakes, helping to slow down and stop the combined truck and camper. This is critical for safety, especially when towing heavier campers.
Auxiliary Power (often twelve-volt positive)
This pin typically provides a twelve-volt power source from the truck to the camper. This can be used to charge the camper’s battery while driving, power interior lights, run small appliances, or operate other twelve-volt devices. It’s essential to know the amperage capacity of this circuit to avoid overloading it.
While color coding can provide a general guideline, it’s vital to remember that wiring standards can vary between manufacturers. Always, always, always verify the function of each wire using a multimeter and consult the documentation that came with your camper and truck for specific wiring diagrams. This is the most reliable way to ensure proper connections.
